MobiDev vs Berezha Security Group: overview
MobiDev
Mobile apps with an applied AI or computer vision component are MobiDev's specialty, delivered from R&D centers in Poland and Ukraine under a company incorporated in both the US and UK since 2009. The company has built a visible specialization in mobile app development and computer vision work for startups and mid-size product companies. That dual-country R&D structure spreads delivery risk but means, like several peers, Ukraine is a delivery location rather than the company's registered domicile.
Berezha Security Group
Three established Ukrainian cybersecurity professionals founded Berezha Security Group in Kyiv in 2014, and unlike nearly every other company on this list, it doesn't build general business software at all: its work is penetration testing, red-team engagements, and security consulting. That narrow focus is exactly what makes it valuable to buyers who specifically need a security audit or offensive-security engagement rather than a development partner, and it is simply the wrong vendor for anyone looking to outsource product development itself.
